Controllers gain edge with external bus interface

Rousset, France: Atmel Corp. added three new microcontrollers to its SAM7 family of ARM7-based USB MCUs. They come in flash-memory densities of 32, 256, and 512kbytes. The SAM7SE microcontrollers are the only ARM7-based MCUs to include an external bus interface that provides access to large amounts of external NAND flash, SDRAM, CompactFlash, SRAM, and ROM storage, claims Atmel.
